Field Detail

SYNCback to summary
public static final WaiterScheduler SYNC

Scheduler implementation that blocks in the schedule method for the given time to pass. This removes the need for a separate threaded scheduler. GenericWaiter can handle the case where schedule blocks, so this will not deadlock or anything.

UNSUPPORTEDback to summary
public static final WaiterScheduler UNSUPPORTED

A WaiterScheduler where waiting is not supported. Always throws an exception. GenericWaiter will still succeed if the wait delay is configured as 0, but not if it's positive.
